The LF18N451 is a very high power handling and efficiency transducer specially designed to provide powerful and accurate sub-bass frequencies with low distortion and low power compression.
Ultra fast time response. The LF18N451 uses a fibre loaded cone assembly along a large triple roll surround, this combination provides remarkable strength and control.
Double silicon spider sysetm ensures excellent control during large excursions.
A fully optimazed T-pole design generate the minimum amount of flux modulation.
The Dual-forced air venting system provides a very efficient voice coil ventilation to minimize the power compression.
Features:
4,5 - inch Inside/Outside copper voice coil
3000 Watt continuous program power handling
97.5 dB Sensitivity
30 Hz - 1 kHz Frequency range
Dual-forced air ventilation for minimum power compression
Dual spider designed with silicon based damping control
BL of 30.2 Txm to provide a faster and accurate low frequency
